Application m it, 1930, Serial No. cam Renewed August 24, 1937 tomobilewheels, and its objects are as follows: I

First, to provide a one-piece arcuate bow of resilient material,preferably metal, which has integral roughened leaves to engage the sidewalls of the tire adjacent to the felly, said how contacting the treadof the tire and having the skid chain temporarily attached to it, theaforesaid engagement of the leaves with the side walls stabilizing thebow and preventing its being twisted out of position when the hardestpull is exerted on the device.

Second, to provide the foregoing device with heels which are adapted torest on the felly to act as fulcrums for pressing the roughened leavesagainst the side walls when the pull of the skid chain tends to rock thedevice.

other objects and advantages will appear in to the accompanying drawing,in which:

Figure 1 is a perspective view of'a portion of the rear end of anautomobile illustrating the application of the device to the.tirepreparatory to laying on the skid chain.

Figure 2 is a detail perspective view showing how the resilient bow isspread preparatory to attaching it to the tire.

Figure 3 is a fractional side elevation of the tire showing the applyingdevice in place, but also illustrating the function of the heels asfulcrums.

It is a common experience with automobile drivers to have difficulty inapplying anti-skid chains, more commonly known as skid chains, becauseit is generally necessary to jack up first one side of the rear axle andthen the other, so that the skid chain can belaid on to the wheel andthe ends followed on around to make the fastening. The instant device isintended to enable the application of a skid chain without having tojack up the end of the axle of the respective wheel.

In the drawing the automobile I has a wheel a 2 with a tire 3 to whichthe skid chain 4 is intended to be applied. This chain isstretched outfull length to the rear of the automobile so that when the applyingdevice plays its part the chain will be drawn upwards and laid on to the50 tread of the tire 3.

The applying device is generally designated 5. It comprises a how 8which goes crosswise of the outside of the tread of the tire 3. The bowhas a pair of integral leaves I (Fig. 2) which, when u the device 5 isapplied to the tire in the intended the following specification,reference being had manner, point in the forward direction of rotationof the wheel. These leaves are internally roughened at 8. The rougheningis of such a nature that it will secure a grip on the side walls of thetire, but the roughening is not in the 5 nature of sharp serrationswhich would cut the tire when pressure is brought to bear.

The bow G and leaves I are made of resilient metal of a suiilcientlyheavy gauge to stand up under the rather rough work that has to be done.10 The tension of the bow is inward so that it will close the leaves Iagainst the side walls of the tire.

A pair of finger grips 9 enable the operator to secure a grip on thedevice (Fig. 2) for spread- 15 ing it preparatory to applying it to thetire. Located adjacently to the finger grips are hooks ill to which theends of the skid chain 4 are temporarily attached. The bow 8 includesheels H which may or may not be made to bear against 20 the wheel 2.When these heels do hear they will actually rest on the margin of theclincher ring on the outside and the corresponding margin of the fellyon the inside.

The operation is readily understood. In order to mount the applyingdevice to the tire 3 the operator grasps the finger grips 9 as shown(Fig. 2), and pulls in opposite directions (arrow a). He then lets go,whereupon the leaves I close in under the swell or the tire (arrow b),firmly gripping the side walls (Fig. 1). The ends of the chain 4 whichwere previously laid out straight,

as already stated, are then hooked on and the automobile is rolledforwardly. This makes the wheel 2 turn in the direction of arrow 0 (Fig.3). The skid chain will be pulled up and over, and when the device 5returns substantially to the original position, it is taken off,whereupon it will be a relatively easy matter to fasten the ends of theskid chain together.

It is to be observed that when the skid chain is pulled up and over theresistance in the direction of arrow d it will tend to turn the devicein the direction of arrow e. It is here where the integral lateralleaves I play an important part. Any tendency which the device 5 mayhave to turn will be prevented by the engagement of the leaves for aconsiderable distance along the side walls of the tire and under theswell thereof.

The lever action thus set up makes the roughening 8 grip the tire sofirmly that no perceptible motion will occur anywhere in the device.This purpose can be accentuated by having the heels ll rest on themargins of the wheel 2. when the foregoing pull occurs in the directionof arrow bow of resilient material to be applied crosswise of the treadof a tire, the ends of the bow having integral, substantially parallelinternally, roughened leaves, and said ends of the bowalso having heelsadapted to rest on the margins of a wheel carrying the tire, and meansat which to hook on the ends 01' a skid chain, said means being carriedby the bow adjacent to the heels so that the pull of the chain willconvert the heels into fulcrums serving to jam the roughened leavesagainst the side walls and prevent twisting of the bow out of position.

2. A skid chain applying device comprising a bow of resilient materialhaving an inward and closing tension; a pair of leaves integral with thebow and extending substantially at right angles from the bow at saidends so as to define heels at the juncture oi the bow with said leaves,said leaves being roughened on their confronting surfaces so as topartially penetrate the tire walls and obtain a flrm grip, and hooksmounted on the bow substantially at the heels for the attachment ofchain ends.
